Lenny,

I asked for the photo of sensor because I would not think a plastic cap should be on it when installed, but I really don't know for sure. I looked at a diagram on AlldataDIY it's below, the sensor is S43 unit and in the diagram I don't see any cover on the the sensor. If you click on the smaller of the two diagrams it has a diagram on the left which shows the sensor installed in the vehicle. Also I'm having a hard time visualizing the orientation of the sensor when it's installed. On your installation it seems like the sensor tip is pointed upward toward the top of the vehicle but in the diagram it seems like the tip is pointed down towards the ground. What do you think?

Edited: I see your vehicle is a 1998. I have Alldata DIY for my 1999 so that may account for the difference.
